T0 (all 11171/0771/ it muy concern:

Be it known that I, PIUDSON BENJIMAN IVHEELER, a citizen of the UnitedStates, residing at Manningtonjn the county of Marion and State of VestVirginia, have invented certain new and useful Improvements in Devicesfor Increasing the Flow in Oil-Wells; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters ot reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in oil-wellapparatus, and especiallyto means whereby an agitation of oil is causedin the pumping operation, whereby a portion of the oil which is drawn upunder the suction of thepump is forced back through leader-pipes andforcibly ejected through the perforated sides of the cylinder andagainst the wall of the well, whereby the paratlin deposited is washedfrom the oil-bearin g rock, thus clearing the way for the ready Iiowingof the oil from. the strata.

More specifically, the present invention resides in the provision of anapparatus of this nature which has a suction-valve in the barrel,through which the oil is drawn, and the provision of externalleader-pipes which allow a portion of the oil to be drawn up by theVacuum formed in the operation of the valve, said leader-pipes conveyingthe oil around the seated valve in the oil-chamber and coming togetherand entering the perforated portion of the oil-chamber through a jet,from which the oil is forced out through the perforated lower portion ofthe sprayingnipple.

To these ends and to such others as the invention may pertain, thesa meconsists, fur.- ther, in the novel construction, arrangement, andadaptation of parts, as will be hereinafter more fully described andthen specifically delined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, inwhich I have` shown, in- Y Figure 1, avertical central section throughthe upper halt' of the apparatus, and in Fig. 2 a similar view ot` thelower section.

. Reference nowbeing had to the details of the drawings by letter, Adesignates the working valve,with suitable ball-valve A therein, saidvalve being connected to the plunger-rod A2. Said valve works in thebarrel B, which has a strainer B2 itted over the shouldered portion bnear the upper end of the member B. The outer circumference of saidbarrel B is screw-threaded and engages with the internal threads B4 ofthe union B9, the lower end of said member being tapered and seated onacorrespondingly-beveled portion of said union, as illustrated in thedrawings. The lower end of said union B9 is internally threaded toreceive the upper threaded end of the cylindrical strainer-tube B7,while the outer circumference of the lower end of said union B9 isexternally threaded, as at B8, which latter threaded portion is designedto engage with the internal threads of the union or collarD, thusleaving a space D outside of the circumference of said strainer BT andbetween the latter and the-inner walls of the union D. The lower end ofsaid strainer-tube BT is fitted into the tube D2, suitable shoulders dbeing provided on the circumference of the said strainer-tube in orderto hold the latter secu-rely in place on the' shouldered portion of thetube D2. Communication is had between the barrel B and the interior ofthe tube BT through the contracted passage-way B10, as-clearlyillustrated in the drawings. On either side of the lower end of saidstrainer-tube B7 kare apertures d through the solid portion of thecollar D, and connected to the lower ends of these apertures ondiametrically opposite sides of the strainer-tube are the leader-tubesE, the connections of said leader-tubes to the apertured portion of thecollar D being shown at E. Connected to the lower end of said tube D2 isthe standing valve-chamber C, made up of two portions threaded togetherand between which is contained the ball-valve C', seated over anaperture, as shown, the upper portion of said chamber having an apertureC2 above the ball-valve and through which oil is allowed to pass to thestrainer-tube above. The lower end of the under section of thevalve-cham- IOO ber C is externally threaded, as at C3, and the.

gage with the threads of said valve-chamber, and the said valve-chambercommunicates Wit-h the perforated barrel H through a contracted orificeH' in the union G, said barrel H being connected to the union G by meansof threaded connections, as shown. At any suitable location below theconnection between the barrel H and valve-chamber C the two leader-pipesE come together in the Y-shaped union J, each of said leaders passingthrough the walls of the perforated barrel and merginginto the centraland downwardlyprojecting pipe J, which has a jet K at its lower end,said jet having shouldered portions in its interior wall and acontracted. outlet K'. Surrounding thisjet is a cylinder K2, which hasthreaded connection with a union carried about the jet, and through thiscylinder are perforations. The lower end of said cylinder K2 hasthreaded connection with a union or collar L, which carries in. itscentral aperture an openended cylinder L', the upper open end of whichcylinder is located, preferably, a slight distance below the lower endof the jet K', as shown in the drawings. M is a union which isscrew-threaded at M' and connected to the barrel H, and in the aperturedsolid portion of said union is supported the lower end of said cylinderL', and to the internal threads at the lower end of said union M isconnected a perforated barrel N of similar construction as said barrelH, and at the lower vend of said barrel N is a plug R, which is providedto cause the oil which is utilized for the purpose of agitation to beforcibly ejected through the. circumferential apertures in said barrelN.-

In operation when the valve A is drawn up the suction formed below thesaid valve will cause the oil to enter the barrel H, through thecircumferential apertures therein, and pass up through the valve-chamber@,throu gh the cylindrical strainer, 'and to follow up through thebarrel B. On the downward throw of said valve a large proportion of theoil that has been drawn up by the suction described will pass throughthe valve A and upward, while aportion of the oil which has passedthrough the perforations in the circumference 'of the strainer B7 willbe forced through the leader-tubes E, which pass outside of thevalve-chamber C, and the streams of oil passing through the leaders willcome together at the union .l and be forced drownward through the pipeJ, leading to the jet K', from which the oil is forcibly ejected'through into the combining-tube or openended cylinder L and be forciblyejected `v through the apertures in the circumference of the barrel Nand against the walls of the oil-bearing rock, which contain theparaffin which is designed to be washed off by the forcible contact ofthe oil against the same, as will be readily understood.

Having thus described my invent ion, what I desire to secure by LettersPaientisl. ln a device for clearing oil-wells, the combination with thebarrel and reciprocating valve therein, a cylindrical open-endedstrainer, a collar connecting the latter with the lower end of saidbarrel, a communicating aperture between said barrel and strainer, aunion having connection with the lower end of said strainer, andthreaded connections with the union connecting the upper end of thestrainer with said barrel, a standing valvechamber connected tothe lowerend of said strainer, a perforated barrel connected to the lowerend ofsaid standing valvechamber, and comm unicatingtherewith, the externalleader-pipes having communication between the space D about thecircumference of said strainer BT and the interior of said perforatedbarrel H, and the said tube with which said pipe connects and thejet-pipe connected thereto and leading to the perforated barrel below,substantially as shown and described.

2. A device for clearing paraffin from oilproducing strata in oil-wells,comprising in combination with the barrel B, the perforated tube B7, theunion D and connections between the latter and barrel B, thevalvechamber within said tube B7, the perforated cylinder H and unionconnecting the latter with said valve-chamber, the leader-pipescommunicating with ducts in the union D and passing through apertures inthe wall of the perforated cylinder, the union connected to the lowerends of the leader-pipes and the pipe J", the jet-pipe K secured to theunion connected to the leader-pipes, the perforated cylinderNand union Mconnecting same with cylinder H, the open-ended tube L mounted in anaperture in the union M, the cylinder K2 having connections with thejet-pipe and said open-ended tube, and the plug R at the lower end ofsaid cylinder N, as set forth.

In testimony `whereof I affix my signature in presence of two witnesses.
